Ubuntu Security Notice 1634-1 - Dwayne Litzenberger discovered that Python Keyring's CryptedFileKeyring file format used weak cryptography. A local attacker may use this issue to brute-force CryptedFileKeyring keyring files. This issue only affected Ubuntu 11.10 and Ubuntu 12.04 LTS. It was discovered that Python Keyring created keyring files with insecure permissions. A local attacker could use this issue to access keyring files belonging to other users. Various other issues were also addressed.

Null sessions are old school. they used to be useful for pretty much every host in a domain. Unfortunately, I very rarely run into an environment where all workstations let you connect anonymously AND get data.

Where they can come in useful is

Against mis-configured servers

Against domain controllers to pull info

Low? actually a medium...

More than once I've had a PT where a master_browser was exposed to the Internet. We were able to connect to the server using rpcclient and enumerate users. After that we had a full list of the users in the domain to conduct external brute forcing attacks with.

If you like pretty pictures, it kinda looks like this, there are command line utilities as well...

Cain uses null sessions by default to try to pull information. On modern systems this will fail.

But domain controllers/master_browsers do allow this, so if you find yourself in the position to be able to speak with one you can a list of users for the domain

You can then take that list of users and do brute force attacks against various services. I rarely don't find at least one username/username in an environment.

Secunia Security Advisory - A weakness and multiple vulnerabilities have been reported in McAfee Email and Web Security Appliance and McAfee Email Gateway, which can be exploited by malicious users to disclose sensitive information and bypass certain security restrictions and by malicious people to conduct cross-site scripting and brute force attacks.

This is a small application built to test the performance of a http authentication system using a lot of concurrent connections. It can also be used to try lots of password against a http server. It is capable of using up to 1024 (or more using multiple processes). However with this amount it is capable or reducing internet connections to a crawl and also greatly increasing the load on the server.

Most hash functions used in hash table implementations can be broken faster than by using brute-force techniques (which is feasible for hash functions with 32 bit output, but very expensive for 64 bit functions) by using one of two "tricks": equivalent substrings or a meet-in-the-middle attack.

Due to computer issues I had to rob some parts from my “electronics” computer, which wasn’t bad, since I was not working on anything at the time and I felt a software project itch. I also wanted to do something with my Apple //c, which resides on my computer desk, so this ghetto brute force [...]

So you spent the big bucks and got that fancy safe but if these guys can build a robot to brute-force the combination you can bet there are thieves out there who can pull it off too. [Kyle Vogt] mentioned that we featured the first iteration of his build back in 2006 but we can’t [...]
